Programmable Camera

Linux-based, programmable cameras from VRmagic (Cambridge, MA) are now available with miniature connectors. For its Linux-based intelligent cameras, VRmagic offers a back end with Picoblade™ connectors for Ethernet, USB 2.0 Host, RS232, and General Purpose I/O Analog Video Output. Additionally, a PCB with DVI or HDMI output can be connected to the cameras. The external board is connected with the PCB stack via a flexible printed circuit cable (FPC). Synchronized image recording and display is also possible via DVI or HDMI up to 60 Hz.

Vision System

The XG-8000 Vision System from the Keyence Corporation (Itasca, IL) features line scan camera models, a high-speed triple core processor, and multicamera connectivity. The XG-8000 offers simultaneous operation of up to 8 cameras. High-load data processing, from 5 megapixel area scan and 8K line scan cameras (capable of capturing 67 megapixel images), is achieved through distributed processing across three high-speed cores. Visual LED indicators display received light intensities and image sharpness, and a new HMI touch panel provides an additional interface option. Users can now choose from direct handheld controller operation and remote desktop through Keyence software or VNC viewer.

Spatially-Invariant Vector Quantization for Image Analysis

A new software tool aims to make computer-aided tissue analysis faster, more accurate, and more consistent. Researchers at the University of Michigan Health System and their colleagues have developed a software tool that aims to make the detection of abnormalities in cell and tissue samples faster, more accurate, and more consistent. The technique, known as Spatially-Invariant Vector Quantization (SIVQ), can pinpoint cancer cells and other critical features from digital images made from tissue slides.

Benefits of a Fully Digital Comparator for Inspection of Orthopedic Implants

This system offers advantages over traditional optical comparators, including the ability for multiple operators to compare parts to the CAD file at any one time.Manufacturers of orthopedic implants take great care to ensure that their products are of the highest quality. One way they do this is by performing numerous inspection operations at various stages throughout the manufacturing process. These have great value — however, they also represent considerable expense. Until recently, implant manufacturers reaped only a small fraction of the potential benefits of these efforts mainly because, in the end, few records of the inspection operations remained. Those that did exist were of poor and irregular quality. This is reasonable, considering in-process inspections are performed on the shop floor by system operators, whose primary function is to manufacture parts. Most inspection records consisted of a few checkmarks on a paper report indicating that the required inspection had indeed been performed successfully. These records do not do justice to industry-wide, high-quality standards.

Quantifying Risk in Various Methods of Continuous Monitoring

Medical device companies should weigh the advantages and disadvantages of different approaches to monitoring critical environments.Worldwide, there is growing concern about how to protect public safety and increase cooperation among regulatory agencies to audit medical device companies and their suppliers. Regulatory agencies are increasingly looking to global organizations such as the Global Health Task Force (GHTF) to adopt harmonization in regulatory practices. As recent as August 2010, the GHTF made medical device suppliers inclusive of site auditing guidelines. (“A supplier delivering materials, components, or services, that may influence the safety and performance of the product.” GHTF/SG4/N33)

Utilizing Machine Vision Engines for Advanced Quality Control and Object Detection

Advanced object and feature recognition eliminates the need for physical probing or fixed sensors.Incorporating machine vision engines into an OEM system with automated handling provides a wide range of benefits to the manufacturer. Machine vision engines are self-contained vision systems that include the optics, lighting, image sensor, electronics, and software to enable standalone “intelligent” decision-making using vision software. Machine vision engines are also much more compact than traditional industrial machine vision systems, which makes them more appropriate for integration into OEM systems with limited space.
